'- formed of suitable sheet metal such Patented May 12, 1931 tiftt fhfi STAE EE JOHN B. ZALLIO, OF CHICAGO, ILLINOIS Application filed "March 18,

My invention has for its general object the provision of an improved food service device which is adapted to permit the stacking of food laden dishes with comparative safety, with a view toward the provision of such an article which 15; simple and well adapted for its purpose.

l ith this ob ect in view my invention conslsts in certain features of n velty in the arrangement of parts by which the said ob ect and certain other ob ects, hereinafter appearing, are ef- L -1 1L L1 e fecteo, all as fully described with reference to the accompanying drawings and more p articularly pointed out 1n the appended clanns.

In the drawmgs Figure 1 is a side elevation of a dish cover embodylng my mvention;

1 3 i the same Figure 2 s a to lan new or Fi ure 3 IS an enlar ed section on the line 0 b o3 of Figure 2;

Fwure t 1s a section on the line l-t of b Figure 3; and

Flgure 5 1s a section on n igure 3.

Like characters of reference mdlcate like parts in the several views.

Referring to the drawings, 1 deslgnates a frusto-conical shell or body, preferably as alumithe line 5-5 of num. See Figures 1 and 2.

lhe edge portion of the upper or small end of the bot y is turned inwardly to form a continuous tubular edge portion 2, and the edge portion of the lower or large end of the body is turned outwardly to form the other coninuous tubular edge portion 3. See Fig. res 2 and 3.

Engaged in these tubular edge portions are non-metallic contact means in the form of soft rubber contact members i spaced along said tubular formations and provided with contact portions 5 spaced correspondingly along said tubular formations and projecting through apertures 6 in the walls of said tubular formations and spaced therealong for contact with upper and lower dishes between which the device is interposed.

Preferably, as shown, the contact portions 5 and the apertures (3 are elongated axially FOOD SERVICE DEVICE 1930. Serial No. 436,671.

of the tubular formations, and the outer surfaces of the contact portions 5 are convex longitudinally of the tubular formations and substantially merge with the outer surfaces of the tubular formations at the ends of the apertures 6 so that they are more sanitary and do not. catch upon a cloth as in the clean ing thereof. See Figures 2, 3 and 4.

Thus it will be seen that the contact members 4 are adequately secured on the body and that only a small portion thereof is exposed, this being conducive to sanitation as well as is the simple continuous form of the device. The contact members 6 engage the dishes between which the device is interposed and tend to prevent slipping thereof, and, spacing the plates from the body of the device, provide for the ventilation of t 1e space inside the device, at the same time adequately onclosing the same.

The tubular formations 2 and 3 are preferably flattened, as designated at 7, to correspond with the portions of the surfaces of the dishes between which the device is interosed. See Figures 1 and 3.

lVhile I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention 1 claim as new and desire to secure by Letters Patent the following 1- Claims:

1. In an article of the character described the combination of a hollow body provided with a continuous tubular edge formation, and contact means engaged in said tubular formation and projecting through apertures in the wall of andspaced along said tubular formation to form spaced contact portions.

2. in an article of the character described the combination of a hollow sheet metal body provided with an integral continuous tubular edge formation and non-metallic contact means engaged. in said tubular formation and provided with contact portions projecting through apertures in the wall of and spaced along said edge formation.

3. In an article of the character described the combination of a hollow sheet metal body provided with an integral continuous tubular edge formation and a plurality of soft rubber members engaged in said edge formation and spaced therealong and provided with contact portions projecting through apertures in the wall of and spaced along said edge formation.

10 4. In an article of the character described. the combination of a hollow sheet metal body provided with an integral continuous tubular edge formation, and soft rubber contact means engaged in said edge formation and provided with contact portions spaced along and elongated axially of said tubular formati on and projecting through apertures in the wall of and elongated axially of and spaced along said tubular formation, the outer surfaces of said contact portions being convex longitudinally thereof and substantially merging with the outer surface of said tubular formation at the ends of said elongated apertures.

5. In an article of the character described the combination of an open sheet metal a nular shell having one edge portion thereof turned inwardly to form a continuous tubular edge formation and having the other edge 3 portion thereof turned outwardly to form the other tubular continuous edge formation, and non-metallic contact means en ged in said tubular formations and prop mg through apertures in the wall of and spaced along said tubular formations to form spaced contact portions.

6. In an article of the character described the combination of an open sheet metal substantially frusto-conical shell having the edge portion at the small end thereof turned inwardly to form a. continuous tubular edge formation and having the other edge portion thereof turned outwardly to form other continuous tubular edge formatiorn and soft rubber contact means engaged in said edge formations and provided with Cont ct portions spaced along and elongatet axially of said tubular formations and projecting through apertures in the walls of and el0n- 5 0 gated axially of said tubular formations, the outer surfaces of said contact portions being convex longitudinally thereof and substantially merging with the outer surf of said tubular formations at the ends of said elon- 5 gated apertures.

In witness whereof I hereunto al'iix my signature this lst day of March. 1930.
